To @ZZ whom t may concern:

Be it known that l, JULES J. REGGIO, a citizen ot the United States, and a resident of New Orleans, in the parish of '@rleans and State of Louisiana, have invented a new and lmproved Trolley-Pole, ot which the following' is a full, clear, and exact description.

rlfhis invention relates to trolley poles and has to deal more particularly Vwith a construction whereby the trolley wheel when it leaves the trolley wire will he automatically lowered to a point below the wire and wire suspension system so as to prevent injury to the latter, trolley wheeler pole.

The invention has for its general objects to improve the construction and operation of devices of this character so as to be reliable and efficient in use, comparatively simple and inexpensive to manufacture, and so designed as to be readily applied to trolley poles already in use, simply hy cutting out an intermediate part thereoi2 and inserting the construction thatv forms the present invention.

A more specific object of the invention is the provision of a trolley pole having an upper section hingedly mounted and provided with an automatic means wherehy the upward throw of the trolley pole, when the wheel leaves the wire, will cause the upper wheel-carrying` section to be released'so th at it will swing down to a position where the wheel will be clear from the trolley wire and the suspension systemftherei'or.

lith such and other objects in view, the invention comprises various novel features of construction and arrangement of parts which will be set 'forth with particularity in the following description and claims appended hereto. v

ln the accompanyinp` drawings which illustrate one embodiment o' the invention and wherein similar characters ot reference indicate corresponding` parts in all the views,

Figure 1 is a side view oi the trolley pole showing the normal position of the parts oit' the trolley pole by full lines and the col-.

la sed position of the parts by dotted lines; iig. 2 is a iront view oi the improved part of the trolley pole;

Fig. 3 is a sectional view on the line 3-3, Fig. 2;

Fig. 4 is a rear view. I Referring to the drawing, 1 designates a trolley wire, 2 the root of any electric car on which is mounted the trolley pole A pivoted on a hase 3 fastened to the roof 2 and operated on by a spring 4l to yielding'ly hold the trolley wheel 5 in underrunninp,` contact with the wire. rllhe trolley pole in the present instance is shown as one that has been in use and an intermediate portion is cut away, and the device a, which constitutes the present invention, is substituted. This device is composed of two rod-like members 6 and 7 hingedly connected by a pivot 8, the 'upper end of the section (i being provided with a socket 9 to receive the upper part 10 of the trolley pole, and the section 7 has a socket 11 at its lower end to receive the lower part 12 ot the trolley pole. By this arrangement the portion of the pole above the pivot 8 can swine; downwardly and rearwardly so that the wheel 5 will be considerably below the trolley wire and suspension system therefor in case the trolley wheel .should leave the trolley wire. y

Normally the members 6 and i' are held in parallel relationhy a catch lfwhich is .pivoted at 111 on the section 7, and the hold ing part of the catch passes through an aperture 15 of the section 6 and has a projection 16 that interlocks with the section 6, as shown by full lines in. Fig.I 1. A spring 17 yieldingly maintains the catch in holding,` position. Attached to the lower end 18' of the catch is a rope 19 that is Vfastened at 20 tothe roof or some other part of the car, and there is suiiicient slack in this rope to prevent any releasing' nill on the catch, but when the trolley pole swings upwardly to an abnormal extent by the wheel leaving` the trolley wire, the catch is released by the rope so that the upper wheel-carrying section of the trolley pole will swing` downwardly, as shown by dotted lines, Fig. 1.

The upper wheel-carrying section is restored to normal position by the trolley pole rope 21, which passes through an aperture 22 in the lower section of the trolley pole and connects at 23 with the section 7 at the side of the pivot 8 opposite from the trolley wheel. V] hen the parts are in the brokenline position, Fig. 1, the downward pull on the rope 21 will iirst swing the section 6 into parallelism with the member 7, and a further pull will cause. the trolley pole to swing downwardly as a unit, and by so doing the catch-operating rope 19 slackens so that the spring 17 will cause the catch 13 to automatically re-set. A guard 211 at the aperture 22 reduces wear on the trolley wheel-carrying section, a lower supportingV rope. The upper part of the member 7 is provided with flaring lugs or ears 25 to guide the section 6 as it becomes seated on the section 7 during the straightening out of the trolley pole after it has been collapsed. f

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will bereadily under- .stood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such Achanges may be made when desired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire. to secure by Letters Patent:

1. A trolley pole composed of an upper wheel-carrying section, a lower supporting section, means for pivotally connecting the sections whereby the wheel-carrying end of the upper section can swing downwardly and rearwardly, a catch for holding the sections in operative position, and a flexible member having one end secured so'as to permit movement in a'vertical direction, the other end being securedv to the catch, the exible member being normally slack and releasing the catch when the trolley pole swings upwardly beyond its normal limit, whereby the wheel-carrying section can be releasedto support the wheel below a trolley wire and its suspension system. Y

2. A4 trolley pole composed of an upper section, means for pivotally connecting the upper section at an intermediate point to the upper extremity of the supporting section, a catch onV the supporting section and releasably engaging the upper section to hold the same in normal position, a carkon which the trolley pole is mounted, and a normally slack element connected with the catch and with the car, whereby the catch is released when the trolley pole swings upwardly beyond a certain point.

3. A trolley pole composed of an upper wheel-carrying section, a lower supporting section, means for pivotally connecting the upper section at an intermediate point to the upper extremity of the supporting section, a catch on the supporting section and releasably engaging the upper section to hold the same inrnormal position, a car on which the trolley pole is mounted, a normally slack element connected -with the catch and with the car, whereby the catch is released when the trolley pole swings upwardly beyond a certain point, and a trolley rope connected with the upper, section at the side of the pivot opposite from the wheel thereon and guided on the supporting section, whereby a pull onthe rope will first reset the sections of the trolley pole and then move the latter downwardly for engaging the wheel thereof with a trolley wire.

4. A trolley pole composed of' a wheelcarrying section, a supporting section on the upper end ot which the wheel-carrying section is pivoted at a point intermediate its ends, a catch pivoted on the supporting section and extending through an aperture in the wheel-carrying section and adapted to engage with the latter, a spring for normally holding the catch in holding position, a normally slack pull device connected .with the catch for releasing thesame when the trolley pole moves beyond a given point, and a trolley pole rope having a slidin engagement with the supporting section an fastened to the wheel-carrying section at the side of the pivot of the latter opposite from the wheel-carryin ortion.
